There are a number of factors that should be considered, among them are the reasons for coverage and the affordability of that coverage. All carriers have financial guidelines that are based on your annual salary and age at application. The younger you are, the more coverage you can qualify for, and the less it will cost assuming your health is good.
Before you apply ask yourself what this insurance must do if you were to die prematurely. Are you single, or married with children? Obviously the need for coverage will be different in each situation. How long should that coverage remain in force?
These are questions to discuss with a good independent agent that can also help with information, and that can lead you to questions that may not have occurred to you.
